Cost-effectiveness of new adult pneumococcal vaccination strategies in Italy
ABSTRACT Community-acquired pneumonia (CAP) and invasive pneumococcal disease (IPD) are very relevant pathologies among elderly people (≥ 65 y old), with a consequent high disease burden. Immunization with the 23-valent pneumococcal polysaccharide vaccine (PPV23) has been differently implemented in the Italian regions in the past years, reaching overall low coverage rates even in those with medical indications. In 2010, the 13-valent pneumococcal conjugate vaccine (PCV13) became available and recommended in the universal Italian infant immunization program. Since October 2012, indications for use of PCV13 were extended to subjects ≥ 50 y to prevent invasive pneumococcal diseases. The Italian decision makers should now revise regional indications for the prevention of pneumococcal diseases in the elderly. Pharmaco-economic analyses represent a useful tool to value the feasibility of new immunization programs and their sustainability. Therefore, an ad hoc population model was developed in order to value the clinical and economic impact of an adult pneumococcal vaccination program in Italy.

ABSTRACT: Pneumococcal pneumonia has a high clinical burden in terms of morbidity, mortality and hospitalization rate, with heavy implications for worldwide health systems. In particular, higher incidence and mortality rates of community-acquired pneumonia (CAP) cases, with related costs, are registered among elderly. This study aimed to an economic evaluation about the immunization with PCV13 in the adult population in Campania region, South Italy. For this purpose we performed, considering a period of 5 y, a budget impact analysis (BIA) and a cost-effectiveness analysis which considered 2 scenarios of immunization compared with lack of immunization for 2 targeted cohorts: first, the high risk subjects aged 50–79 y, and second the high risk individuals aged 50–64 y, together with all those aged 65 y. Regarding the first group, the decrease of pneumonia could give savings equal to €29 005 660, while the immunization of the second cohort could allow savings equal to €10 006 017. The economic evaluation of pneumococcal vaccine for adult groups represents an essential instrument to support health policies. This study showed that both hypothesized immunization strategies could produce savings. Obtained results support the use of pneumococcal conjugate vaccine for adults. This strategy could represent a sustainable and savings-producer health policy.Human Vaccines & Immunotherapeutics 11/2013; 10(2). DOI:10.4161/hv.26888 · 3.64 Impact Factor

ABSTRACT: Diseases caused by Streptococcus pneumoniae (pneumococcus) are a major global public health problem. Despite their importance, information on the burden of the different pneumococcal diseases is limited and estimates vary widely. We critically reviewed the full economic evaluations (FEEs) on the new pneumococcal conjugate vaccines (PCVs) conducted in the European Union (EU) to assess their potential contribution to public decision making. We selected the FEEs focussed on PCV-10 and PCV-13 and published in English from January 2007 until June 2013. We screened the selected articles to assess their main methodological features using a common checklist composed of epidemiological, clinical and economic items. All the ten studies selected were based on modelling and the time horizon was always long term. Two studies focused on adults, the remaining eight on infants. Only one study based herd immunity on national data, eight used foreign data or modelling and the last did not consider it. National prices and tariffs were claimed to be sources for unit costs in all studies; however, half of them assumed price parity when one vaccine was not yet marketed, and the figures varied within the countries where more than one study was conducted. Conclusions supported the economic utility of pneumococcal vaccination in all studies, raising some concern only in (i) the independent study, which found that PCV-13 was borderline cost effective, and (ii) the study sponsored by both manufacturers, which estimated an incremental ratio slightly above the national threshold for both PCV-10 and PCV-13. The European studies we analysed are mostly based on weak sources of data. Because of the limited information on vaccine effectiveness and lack of epidemiological and economic data, the need for extensive recourse to assumptions leads to great within- and between-study variability generated by authors' choices.PharmacoEconomics 11/2013; 32(1).
